University of Arizona entomologist Katy Prudic calls some hammer orchids of Australia downright “kinky” in how they seduce wasps into pollinating.

The orchids have a central petal that resemble female thynnine wasps and give off a sexy wasp scent. Unsuspecting male wasps then swoop in to pick up the supposed female, both literally and figuratively.

“Wasp females have no wings and stay close to the ground when releasing pheromones,” says Steven Handel, an evolutionary ecologist at Rutgers University via email. For this reason, the bird orchid also grows low to the ground.

In experiments published in the journal Oecologia, Handel and colleagues found that bird orchids raised higher off the ground did not attract male wasps—presumably because they know females never fly.

It's pollinated by blood-sucking sandflies “who think the same thing,” she says. The fly crawls in the plant’s fuzzy, veiny, ear-like tube thinking it’s getting a blood meal and is trapped for the night, only to be released the next morning covered in pollen.
